 +
 +[[https://github.com/analogdevicesinc/aditof_sdk/tree/master/examples/aditof-demo | This example]] demonstrates how to capture data from the TOF system on the Nvidia jetson and display it using OpenCV. 
 +
 +Once Linux boots you'll see on the HDMI monitor the Linux desktop and on the top left corner a shortcut to the evaluation application. Double clicking on the icon will start the evaluation application. A console window will open to show the application's status and, after a few seconds, the evaluation application GUI will be displayed.
 +
 +{{:resources:eval:user-guides:ad-96tof1-ebz:aditof_demo.png|}}
 +
 +When starting the application, a terminal window will open to display status messages (also warning and error messages, in case there are any issues). Shorty the main window will show up.
 +
 +The evaluation application allows to do live streaming of depth and IR data as well as recording the depth and IR data and playing back from a file. The depth data is displayed as a color map ranging from warm to cold colors as the distance from the camera increases. A point in the middle of the depth image shows the distance in mm to the target.
 +
 +There are 3 operating modes that determine the range of the system:
 +
 +  * Near - 25cm to 80cm
 +  * Medium - 30cm to 3m
 +
 +When in a certain operating mode the system will measure distances outside of the mode's range but those will not be accurate. The evaluation application also displays the temperature in deg C of the camera (AFE).
 +
 +The framerate at which data is acquired from the system is constantly updated on the GUI. The camera board outputs data at 30 frames per second (fps), but due to USB connection limitations, the host PC acquires the frames at a lower rate.

----- +  * The demo application hangs after closing the main window 
-===== Running the evaluation application =====+    * Due to some limitations the application always hangs if it is closed using the regular X button from the window top bar (title bar). To avoid this unpleasant hang, we've made available a second X button in the top right corner right above the title bar that can be used to safely close the demo application. We hope this to be a temporary workaround.
  
-[[https://github.com/analogdevicesinc/aditof_sdk/tree/master/examples/imshow-jetson | This example]] demonstrates how to capture data from the TOF system on the Nvidia jetson and display it using OpenCV. Due to limitations in the Nvidia Jetson software infrastructure for MIPI virtual channels support, only one video stream is available at a time, depth or IR.
